Sclerophrys garmani, also known as Garman's toad or eastern olive toad (among others), is a species of toad in the family Bufonidae. It is widely distributed in East and Southern Africa. However, populations north and south of Tanzania might represent distinct species. If so, the name Sclerophrys garmani would apply to populations from northeastern Africa. Furthermore, its southern boundary towards the range of Sclerophrys poweri in South Africa is also unclear.
The specific name garmani honors Samuel Garman, an American ichthyologist and herpetologist. Males grow to 106 mm (4.2 in) and females to 115 mm (4.5 in) in snout–vent length. The tympanum is almost as big as the eye diameter. The parotoid glands are large. The back is tan to olive-brown and bears large paired markings edged with black. A thin vertebral stripe may be present. Dorsal skin has distinct warts that bear small, black spines. The ventrum is off-white.
The male advertisement call is a loud, low-pitched "kwaak", lasting for about a second. The range extends from Ethiopia and Somalia southward through Kenya, Tanzania, Mozambique, Zambia, Zimbabwe, Botswana, to South Africa... Wikipedia →

| # | Park | Country | Daily sighting probability |

Possible
About 30% of wildlife watchers report a Garman's Toad sighting in Gonarezhou National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 5 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Garman's Toad in Gonarezhou National Park on a given day, against under 5% in July to October, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Garman's Toad sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 3 parks where we can rate Garman's Toad sightings, Gonarezhou National Park has the highest daily chance: about 30%. Next come Kruger National Park (South Africa, about 20%) and iSimangaliso Wetland Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the Garman's Toad is recorded against all the amphibians logged in Gonarezhou National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
